利用光学设计软件Zemax构建了轴长和角膜前表面曲率不同比例的五种+6.00 m-1的远视模型及框架眼镜矫正模型, 分析镜片中心产生偏移时的像差情况.结果表明: 对于+6.00 m-1的远视性弱视而言, 当镜片中心偏移大于4 mm时, 其产生的球差、像散和畸变开始对矫正视力产生影响.镜片偏移带来的球差在轴性远视所占比例高的模型中表现明显, 而畸变和像散在各种模型中的作用没有明显差异.在远视性弱视矫正过程中, 需要检测角膜曲率及轴长数据, 分析其在屈光不正形成中所占的比例, 合理选择个性化定制的非球面镜片, 从而保证弱视的治疗效果.

The +6.00 m-1 hypermetropia models and correction models were built by changing axial length and corneal curvature of the anterior surface using optical design program Zemax. Based on the correction models, the aberrations which were due to the central deviation of corrective lens were analyzed. For the +6.00 m-1 axial hypermetropia, when the lens offset is more than 4mm, the spherical aberration, astigmatism and distortion are beginning to affect vision. Because of the central deviation of corrective lens, the spherical aberration is obvious in the model which is high percentage of axis changing, while the distortion and astigmatism are no significant difference in various models. These aberrations will reduce the treatment of amblyopia. During the correction of the hyperopic amblyopia, it is necessary to measure the anterior surface radius of cornea and the eye axial length. According to the composition proportion of the refractive error, aspheric lens is designed individually for the hyperopic amblyopia in order to ensure the treatment of amblyopia.
